Enclosed Thimbles

[Ted Reshetiloff]

Had no luck searching so I will ask here. I am trying to locate an enclosed thimble for my anchor rode. I have 3/4" nylon 12 strand going to about 20' of 3/8 chain. The existing thimble was a nylon one of poor quality and did not hold up well. I want to replace the thimble and wish to use an enclosed thimble of either stainless or galvanized steel. I believe an enclosed thimble will prevent the line from slipping the thimble out but do not see them available in the more common chandleries. Is this something you make your self by welding tabs over an open thimble?
